Laser Pulse Generator
Features
Time-resolved diagnostics of high speed optical detectors
Trigger input and synch output connector
Lens control allows the beam to be de-focussed and
spread across the detector area
Variable width control allows pulse widths from 40 ps
up to 800 ps
Applications
Time response of high speed photomultipliers
Gating measurement of image intensifiers
General Description
The Photek Laser Pulse Generator (LPG) is designed for time resolved diagnostics of photomultipliers and
image intensifiers. The LPG in conjunction with a digital delay/pulse generator (not supplied) can test both
the time response of high speed photomultipliers and the gating speed of image intensifiers. The LPG
features a lens control which allows the beam to be de-focussed and spread across the detector area and a
variable width control for pulse widths between 40 ps to 800 ps. The LPG uses a laser diode with either a
wavelength of 405 nm or 650 nm, other wavelengths are available on request.
